1. A system for monitoring conditions within a tire comprising:

  • a sensor assembly disposed within each tire of a motor vehicle, a transmitter in communication with said sensor assembly to transmit a frequency shift keyed transmission indicative of current tire conditions;

    a remote transmitter for actuating a remote keyless entry system, said remote transmitter emitting a amplitude shift keyed transmission to actuate a function of said keyless entry system;

    a receiver assembly for receiving said frequency shift keyed transmission signal indicative of said current tire conditions and said amplitude shift keyed transmission signal to actuate a function from said remote transmitter, said receiver assembly including an amplitude shift keyed receiver, and a frequency shift keyed receiver, said amplitude shift keyed receiver and said frequency shift keyed receiver are selectively engaged in receive incoming signals in response to a predetermined triggering event wherein said transmission indicative of current tire conditions includes an amplitude shift keyed wake-up signal for alerting said receiver assembly of an incoming frequency shift keyed transmission signal such that said amplitude shift keyed wake-up signal initiates a switch from said amplitude shift keyed receiver to said frequency shift keyed receiver.
